Recording apparatus for recording data to recording medium with a Plurality of clusters

Abstract

A recording apparatus includes a recording unit configured to record moving image data including a plurality of frames on a recording medium. The recording medium includes a plurality of clusters. The apparatus also includes an editing unit of the moving image data, a setting unit configured to optionally set the editing unit, a management information processing unit configured to generate management information including link information indicating a cluster number of the moving image data to be reproduced next with respect to a plurality of clusters having the moving image data recorded thereon, and a control unit configured to control the recording unit to record a front frame of each editing unit in the moving image data on an area beginning with a cluster of the recording medium based on the editing unit set by the setting unit.

What is claimed is: 
     
       1. A recording apparatus comprising:
 setting means for setting a unit of time length of moving image data including a plurality of frames, the unit of time length including at least one frame of the moving image data; 
 a time length instruction unit configured to provide an instruction for changing the unit of time length, the setting means changing the unit of time length in accordance with the instruction for changing the unit of time length provided by the time length instruction unit; 
 a recorder configured to record a moving image file including the moving image data on a recording medium including a plurality of clusters, the recorded moving image data of one moving image file including a plurality of the units of time length set by the setting means; 
 a management unit configured to generate management information containing a link information indicating a cluster number of the moving image data to be reproduced next with respect to a plurality of clusters in which the moving image data are recorded; and 
 a controller configured to control the recorder in accordance with the unit of time length set by the setting means so as to record a front frame of each of the plurality of units of time length included in the moving image data of one moving image file on a front of a cluster of the recording medium. 
 
     
     
       2. A recording apparatus according to  claim 1 , wherein the controller controls the recorder to record padding data on a free area other than a recorded area where the moving image data are recorded in a cluster which a last frame of the unit of time length of the moving image data are recorded. 
     
     
       3. A recording apparatus according to  claim 1 , further comprising a deletion instruction unit configured to issue an instruction to delete a part of moving image data recorded on the recording medium, the deletion instruction unit determines the part of the moving image data to be deleted in accordance with the unit of time length, wherein the management unit changes a content of the management information in response to the instruction from the deletion instruction unit. 
     
     
       4. A recording apparatus according to  claim 1 , wherein the setting means selects the unit of time length from among a plurality of predetermined time lengths. 
     
     
       5. A recording apparatus according to  claim 1 , further comprising a display unit configured to display an information indicative of the unit of time length set by the set means during recording of the moving image data. 
     
     
       6. A recording apparatus according to  claim 1 , wherein the recorder records an information indicative of the unit of time length set by the setting means on the recording medium. 
     
     
       7. An imaging apparatus comprising:
 an imaging unit configured to generate moving image data including a plurality of frames; 
 setting means for setting an unit of time length of the moving image data, the unit of time length including at least one frame of the moving image data; 
 a time length instruction unit configured to provide an instruction for changing the unit of time length, the setting means changing the unit of time length in accordance with the instruction for changing the unit of time length provided by the time length instruction unit; 
 a recorder configured to record a moving image file including the moving image data on a recording medium including a plurality of clusters, the recorded moving image data of one moving image file including a plurality of the units of time length set by the setting means; 
 a management unit configured to generate management information containing a link information indicating a cluster number of the moving image data to be reproduced next with respect to a plurality of clusters in which the moving image data are recorded; and 
 a controller configured to control the recorder in accordance with the unit of time length set by the setting means so as to record a front frame of each of the plurality of units of time length included in the moving image data of one moving image file on a front of a cluster of the recording medium. 
 
     
     
       8. A method for controlling a recording apparatus having a recording unit, the method comprising:
 setting a unit of time length of moving image data including a plurality of frames, the unit of time length including at least one frame of the moving image data; 
 changing the unit of time length in accordance with an instruction for changing the unit of time length provided by a time length instruction unit; 
 controlling the recording unit to record a moving image file including the moving image data on a recording medium including a plurality of clusters, the recorded moving image data of one moving image file including a plurality of the units of time length; 
 generating management information containing a link information indicating a cluster number of the moving image data to be reproduced next with respect to a plurality of clusters in which the moving image data are recorded; and 
 controlling the recording unit in accordance with the unit of time length so as to record a front frame of each of the plurality of units of time length included in the moving image data of one moving image file on a front of a cluster of the recording medium.
